It's a grey area ihmo.
A portscan is just a nock on a appartment door, and just waiting whom is
going to openup. Besides that, it's nothing more. And you can see this as
annoying, nocking on someones door and then running like hell, but.. then
again, no harm is done.

Good point. The only other problem is that our department is looking for
ways to cut back and so asking for _anything_ to my immediate superiors
seems risky in their eyes.
Certainly there are people on their level in other departments who
wholeheartedly agree with me and even the people right abo

We have one machine that is currently handleing about that many users.
It runs Debian 3.0 stable, sendmail, spamassassin (if anyone has a
better spam fillter let me know), imap and pop, and the load average is
rarely above 0.7. Most of the load comes from spamassassin. Which
seems to be normal.

There are also cheap ($100) NAT routers / "firewalls" available like
D-Link or Netgear if you don't need a speed > 10Mbps
You'll have to spend $100, but it won't consume you time, it takes a lot
less space, and it will consume a lot less electricity.

Can anyone give me any figures on how much machine I need to serve as a
mail server for N users?

Your question is certainly quite vague, but here are a few things to think
about..
What mail delivery program are you thinking of using and are you planning on
providing pop3 and/or imap service? Imap requires more processing power to
display the mail folders, but it depends on the software again
If its of any help, at my last firm, we had 1000 email domains all using
different setup's their were 900 pop accounts checking their mail every
5 - 10 mins our set up was
Sendmail 8.11
Debian 3.0 kernel 2.4.18
intel 550Mhz
256Mb Ram
40Gb Hd
Machine load never above 0.7
